“…11,12,35 Recent epidemiologic data showing that extraorbital sebaceous carcinoma has a reduced tendency for regional metastasis (1.4% for extraorbital vs 4.4% for periorbital) supports this theory. 69 Highly aggressive extraorbital sebaceous carcinoma has been reported in the literature, 40,82,116,[139][140][141][142] and regular follow-up after complete excision is still required to monitor for regional or distant metastasis. 69 Highly aggressive extraorbital sebaceous carcinoma has been reported in the literature, 40,82,116,[139][140][141][142] and regular follow-up after complete excision is still required to monitor for regional or distant metastasis.…”
